Abstract: ABSTRACT OF THE DISCLOSURE An object has a light reflected or emanating therefrom projected through a symmetrical imaging device.  The symmetrical imaging device contains a reference plane where the light impinging thereon has its direction changed or altered.  The symmetrical imaging device relative to the reference or symmetry plane has optical properties restricting the transmitted ray from the symmetrical imaging device to lay into a normal plane containing the incident ray and the normal to the reference plane at the point of incidence.  The angle of incidence is equal to the angle of transmission, but is contained on the same side of the normal (where the angle of incidence is the angle between the incident light ray and normal, the angle of transmission is the angle between the reflected light ray and normal).  In the retroreflecting aspect of this invention, each light ray is reflected precisely back upon itself before or after this light ray is specularly reflected by a partially transparent medium which surface is usually coinciding with the aforementioned reference plane.  In the light deflection form of the invention that uses deflection or reflection or a combination of these aspects for transmission; the device has a plane shape rather than a box shape and light from an object on one side of the device will be thrown to the opposite side of the device rather than sideways to the device in both cases.  In either case, the light projected by the device forms images of objects in space.  In the case of a retroreflecting device, light must be detoured as by a beam splitter, to produce a symmetrical image capable of having dimensional qualities.

Abstract: LIFTING SYSTEM FOR ADJUSTABLE HOSPITAL BED                ABSTRACT OF THE DISCLOSURE      Independently operable lifting mechanisms are provided at the head and foot ends of the fixed lower base frame of an adjustable hospital bed in order to facilitate independent height adjustment of the head and foot ends of the bed's movable upper frame.  The two lifting mechanisms are actuated by respective ones of two drive screws which may be rotated individually or simultaneously and in either direction to position the upper frame at any desired height and at any selected tilt angle.  In other words, by turning only one of the drive screws one end of the upper frame is elevated or lowered and the tilt angle will be changed.  By rotating both of the drive screws at the same time the upper frame will be raised or lowered at a constant tilt angle.  This flexibility enhances the medical treatment that a hospital patient may receive.

Abstract: Abstract of the Disclosure A silver-halide/gelatin light-sensitive emulsion containing a saturated cyclic oxime compound, and optionally containing a di- or tri-methylol lower alkane compound is disclosed.  The saturated cyclic oxime compound significantly increases the covering power of the silver in the silver halide emulsion and thereby allows for a decrease in the amount of silver used.  Including a di- or tri-methylol lower alkane compound in the emulsion reduces or prevents the generation of fog during coating and fast drying of the emulsion.  The light-sensitive emulsion coated on a substrate is particularly useful as a radiographic film.

Abstract: RECIRCULATING AIR HEATER               Abstract of the Disclosure A recirculating air heater for an oven is fired by a burner and connected with the oven by a re-turn air duct and an outlet duct.  The return air duct has two sets of louvers for admitting controlled amounts of return air to a combustion chamber and a burner by-pass chamber in the oven.  The combustion gases and re-turn air in the combustion chamber are mixed and direct-ed through a catalytic converter before being mixed with the return air in the burner bypass chamber and directed back into the oven.  A portion of the gases directed through the catalytic converter are discharged to atmos-phere and an equal amount of preheated fresh air is admitted to the heater.  The inlet and exhaust ducts are provided with blowers and dampers so that the mass flow rates of fresh air and exhaust air are substantially equal.  During oven preheating some of the combustion gases and heated return air are caused to bypass the catalytic converter and flow directly back into the oven

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to an improvement in a metal strip rolling apparatus.  The metal strip rolling apparatus consists of a rolling mill, a tension take-up reel to receive the metal strip passing through the mill, and a shape sensing roll mounted between the mill and the take-up reel,  The shape sensing roll provides information for adjusting the mill for correction of the shape of the metal strip in the mill.  The improvement consists of a closed loop system for automatically adjusting actual wrap angle of the metal strip on the shape sensing roll.  The closed loop includes hydraulic lifts, disposed at either end of the shape sensing roll, for adjusting the position of both ends of the shape sensing roll simultaneously relative to the position of the take-up reel, servo actuator controls the operation of the hydraulic lift.          An electronic processor receives information from the shape sensing roll relating to its actual wrap angle, and it has in its memory a quantity indicative of a desired wrap angle.          Thus, when actual wrap angle is different from desired wrap angle, the processor will actuate the servo to control the hydraulic lift to adjust the position of the shape sensing roll to eliminate the difference.

Abstract: Abstract of the Disclosure A microwave sterilizer for sterilizing a connector or coupling that interconnects a first conduit from a source of liquid to be infused into a living body to a second conduit implanted in the body.  The apparatus of the invention comprises a housing having first and second members forming a guided wave structure adapted to be removably closed around the coupling or connector and further including first and second clamping means.  The clamping means are adapted to clamp respective conduits and are operable to isolate a charge of the liquid within the connector.  A microwave source is used to generate energy which in turn is coupled to the guided wave structure to cause heating of the liquid charge to a temperature level to cause sterilization so as to destroy substantially all form of bacteria therein.  After a predetermined heating sequence, the apparatus is released and the bag side clamping means is first released so as to pass the sterilized charge of liquid into the source or bag.
